Pool Pump Motor Replacements

The useful life of a pool pump motor is around 8 years. When your motor begins to make squeaking sounds or won’t turn on, it likely means you need to replace it. When selecting a replacement motor, you must match the Horsepower (HP), Frame (FR), and Service Factor (SF, up-rated or full-rated motor). Inyo Pools can help you select the right motor and carries a wide range of replacement pool pump motors for many brands, including:

• Pentair - SuperFlo, IntelliFlo, WhisperFlo, and Challenger.

• Hayward - Super Pump, Super II, TriStar, and MaxFlo

• Jandy - Stealth, FloPro, and PlusHP

• Sta-Rite - SuperMax, Max-E-Pro, and Dura-Glas

• Waterway - Champion, Executive, and Hi-Flo

• Jacuzzi - Magnum, LR / SLR Series, Cygnet

Single-Speed Motors

These motors have only one speed and are the most common type of pool pump motor. They operate at a constant speed (3450 RPM), consuming the most energy of the three motor types. Single-speed motors are the least expensive pool pump motor design. Single-speed motors can be controlled by a standard Intermatic pool timer, pool automation system, or wired to a light switch.

Dual-Speed Motors

These motors can run at a high speed (3450 RPM) or low speed (1725 RPM), making them more efficient than the single-speed motor. For optimal energy efficiency, the dual-speed motors are scheduled to run at low speeds most of the time. Though the low speed is half the RPM load as the high speed, low speed uses as little as 1/8th of the power. Dual-speed pool pump motors require a dual-speed mechanical timer, digital Intermatic timer, or a mounted switch to control the on/off and hi/lo functions.

Variable-Speed Motors

These motors can run at different speeds, which allows them to consume less energy and operate more quietly than single-speed motors. They are the most expensive option but can save you money in the long run by reducing your energy costs. Some variable-speed motors also come with programmable features that allow you to set the pump to run at specific speeds at different times of the day.

Want to Upgrade Your Single-Speed Motor to Variable Speed?

Inyo Pools has made upgrading your old single speed pool pump to a variable speed with our NEW Variable Speed Upgrade kits. Inyo’s VS Motor Kits include Century’s EVO V-Green VS Motor (1.65 HP or 2.2HP), Seal Kit with heavy-duty saltwater shaft seal, impeller, and any other parts required to make the switch.

Replacing a pool pump motor is a task that can be completed with the right tools and some basic knowledge of electrical wiring. Here are the general steps to follow:

1. Turn off the power supply to the pool pump. This may involve switching off the circuit breaker that powers the pump or unplugging the pump from its power source.
2. Disconnect the old motor from the pool pump. This will usually involve unscrewing the bolts or screws that hold the motor to the pump housing.
3. Remove the impeller from the old motor shaft. This may require a specialized tool, such as an impeller removal tool or a pair of pliers.
4. Install the impeller onto the new motor shaft. This may also require a specialized tool, such as an impeller installation tool or a pair of pliers.
5. Attach the new motor to the pump housing using bolts or screws.
6. Reconnect the electrical wires to the new motor. Make sure to connect the wires according to the wiring diagram that came with the new motor. This is important to ensure that the motor runs properly and safely.
7. Test the new motor to make sure it is functioning correctly. You can do this by turning on the power supply to the pump and observing the motor's operation. If everything is working correctly, the motor should start up smoothly and pump water through the system.
